Flash flooding in Ellicott City came days after county officials announced plans to install sensors that would help predict disasters and get warnings to residents faster.
Ellicott City is one of three locations chosen by the U.S. Department of Homeland Security for a pilot program that would create a better warning system.
Homeland Security and the National Weather Service planned to install 48 sensors across the area that would detect water levels.
The goal is to get more data about how weather impacts the watershed to help predict flooding in advance.
The first installation was scheduled for next month.
